Re: linux-4.7-1 breaks X on i915-based Samsung laptop

Thanks loqs, I just didn't notice your edit and mail notifications seem to ignore the edits.
Building right now, I'll give some feedback asap.

pkgver() complains about not finding tags (annotated and un-annotated), I removed the entire function, using

pkgver() {
  cd "${_srcname}"
  printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
}

would be better, though.

[edit: fix pkgver dir]

[update]
I finally build and install that kernel, it seems to work.
If someone needs any detail, please ask.
It takes more than two hours to build the kernel with the config supplied with linux-git (damned modules) so I suggest to edit it.
Please try the patched kernel and report.

If someone doesn't want to build the kernel from scratch, but want to try it out, I can upload x86_64 binaries somewhere (yes, you have to blindly trust me)

These patches unfortunately not yet included in the official kernel.

Thanks loqs for the patch.

Is there any chance to get your patch in the official kernel?

Thanks loqs for the patch.

It is by Ville Syrjälä not me see https://github.com/vsyrjala/linux/commi … d2532b0c96

Is there any chance to get your patch in the official kernel?

I do not have the hardware to test it on so.  So for me to make the request I would be be doing it without being able to personally verify it works.
The patch as part of a larger collection of fixes has entered the mainline tree https://git.kernel.org/cgit/linux/kerne … a018c97b8d
Not seeing it in the stable tree https://git.kernel.org/cgit/linux/kerne … table.git/
There is a chance that the maintainer would include the patch if you could verify it applies cleanly to 4.7.x and fixes the issue. Although that would go against the Simplicity principal as stable has not picked the patch up.
In the interim you can patch the kernel yourself or use the lts kernel.
Edit:
Corrected link to commit for the mainline kernel.

Re: linux-4.7-1 breaks X on i915-based Samsung laptop

Today I've just upgraded the kernel from 4.6.5-1 to 4.7.6-1 and the issue seems to be fixed.
I was able to start the X without any error.

I guess this thread can be marked as [SOLVED]
